SETTING STRUCTURE FOR LUMBER IIILNS:y AND THE LIKE.

Application led February 16, 1924. Serial No. 693,282.

This invention relates to setting struc-tures for lumber kilns and the like.

Heretofore, set-ting structures for kilns and the like have been made With a heat iiisulating coating on the outside of the setting, with theresult that the inner usually porous surface of the setting was subjected to the injurious action of the intense heat and abundant moisture Within the kiln compartments, and the outside heat insulating coating was subjected to the deteriorating effects of the elements and climatic changes.

The object of the present invention, therefore, is to provide an improved setting structure for lumber kilns and the like which suocessfully overcomes the above and other disadvantages of setting structures now in use by forming the structure with aheat insulating coating on the inner surface of the setting. As a result, the life and effectiveness of the structure are materially prolonged. y

Further objects of the invention are in part obvious and in part Will appear more in detail hereinafter.

In the drawing, which represents one suitable embodiment of my invention, Fig. l isl a cross sectional view of a tivo-compartment lumber kiln; and Fig. 2 is a fragment-ar perspective view` thereof.

In the present embodiment of the inven-` tion, the settings o-f the kiln are of brick Work, the kiln comprising side Walls l, a rear Wall 2, a front Wall 3, and av centrally disposed, longitudinally extending partition 4 dividing the kiln into tivo `compartments 5. The front Wall 3 is provided with tivo doors 6, providing access to each of the compartments.

In order to seal the compartments against the escape of heat, the inner porous surfaces of the side and end settings are each pro- In vided with a. heat insulating coating. the present embodiment, this coating com.- prises a primer coat 7 in liquid form, which is brushed onto or otherwise suitably applied to the brick Work to seal the pores thereof, and a second or finishing coat 8 in plastic form, which is applied to the primer coat by a troWel or the like.

A primer coat which has been found particularly satisfactory for this purpose is made of pine oil and the asphalt material known as uintaite or gilsonite, While a satisfactory finishing coat is made up of asbestos fibres,'gilsonite and pine oil. While the heatv insulating coating so formed may be'of any suitable thickness, a thickness of one-eighth of an inch has been found to be satisfactory.

Lumber kilns and the like are often conand as all of the compartments may notbe in use at the same time., it is desirable that each compartment be sealed, so that the heat in any one compartment cannot escape into other and perhaps then idle compartments. My improved sett-ing struct-ure should, therefore, be used for the kiln partitions, both surfaces of each partition setting being provided Witli a heat insulating coating above referred to.- yl/Vhile a setting structure With only one surface of the setting provided With ystructed with a plurality of compartments,

It Willthus be seen that I have provided a i setting struc-ture for lumber kilns and the like in which the several kiln compartments are effectively sealed against the escapeof heat, and in which the inner porous surface of the setting is not subj eoted to the injurious action of the intense. heat and abundant moisture Within the kiln compartments, and the heat insulating coating is not subjected to the deteriorating action of the elements and climatic changes.

Other advantages of the invent-ion will be apparent to those skilled in the art to Which Vit relates.

What I claim is: l. A setting structure for lumber kilns wherein considerable heat and moisture are thereof, said coating comprising a primer coat of gilsonite and pine oil and a finishing coat of asbestos fibres, gilsonite, and pine oil. coa-t applied in liquid form made up of gil 2. A setting structure for lumber kilns sonite and pine oil and a. finishing coat apwherein considerable heat and moisture are plied in plastic form made up of asbestos l0 encountered comprising a setting of porous fibres, gilsonite and pine oil. 5 material and av heat insulating and moist-ure In testimony whereof I hereby affix my proof coating applied to the inner surface signature. thereof, said coating comprising a. primer JACOB M.
